lorcana-simulator

Download and inspect a single turn of a real Lorcana game from production using the `tcg-replay` CLI. Use whenever you need to understand what actually happened in a player-reported bug — gives you the cards involved (with file paths), the pre-turn match state, and a step-by-step trace of moves, engine logs, and JSON patches for that turn.

What to adapt for (mobile, tablet, desktop, print, email, etc.)

The feature or component to animate (optional)

The feature or area to audit (optional)

Configure Better Auth server and client, set up database adapters, manage sessions, add plugins, and handle environment variables. Use when users mention Better Auth, betterauth, auth.ts, or need to set up TypeScript authentication with email/password, OAuth, or plugin configuration.

Configure rate limiting, manage auth secrets, set up CSRF protection, define trusted origins, secure sessions and cookies, encrypt OAuth tokens, track IP addresses, and implement audit logging for Better Auth. Use when users need to secure their auth setup, prevent brute force attacks, or harden a Better Auth deployment.

The feature or component to make bolder (optional)

The feature or component with unclear copy (optional)

The feature or component to colorize (optional)

Scaffold and implement authentication in TypeScript/JavaScript apps using Better Auth. Detect frameworks, configure database adapters, set up route handlers, add OAuth providers, and create auth UI pages. Use when users want to add login, sign-up, or authentication to a new or existing project with Better Auth.

The feature or area to critique (optional)

The feature or area to add delight to (optional)

The feature or component to distill (optional)

Configure email verification, implement password reset flows, set password policies, and customise hashing algorithms for Better Auth email/password authentication. Use when users need to set up login, sign-in, sign-up, credential authentication, or password security with Better Auth.

The feature, component, or area to extract from (optional)

Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications. Generates creative, polished code that avoids generic AI aesthetics.

The feature or area to harden (optional)

Diagnose and fix Lorcana parser/generator gaps in `packages/lorcana/lorcana-cards` when card implementations are blocked by missing parsing coverage, manual-override mismatches, or generation stubs. Use for requests like "fix parser", "improve generator", "unblock missingImplementation cards", or "why is this card unparseable".

Link workspace packages in monorepos (npm, yarn, pnpm, bun). USE WHEN: (1) you just created or generated new packages and need to wire up their dependencies, (2) user imports from a sibling package and needs to add it as a dependency, (3) you get resolution errors for workspace packages (@org/*) like "cannot find module", "failed to resolve import", "TS2307", or "cannot resolve". DO NOT patch around with tsconfig paths or manual package.json edits - use the package manager's workspace commands to fix actual linking.

Single owner for everything related to a specific Disney Lorcana card in `packages/lorcana/lorcana-cards` — authoring, debugging, triaging, generating, and any bounded engine or types extension required to make the printed text work. Use whenever the unit of work is "this card".

Explain and cite Disney Lorcana rules using indexed references, and produce implementation-ready behavior constraints for card development. Use when answering mechanic questions, resolving card interactions, or deriving test/implementation constraints from official rules.

Generate focused Lorcana card-behavior tests using the current multiplayer test engine and helper syntax, and write minimal engine repro tests when a card exposes a suspected runtime gap.

Monitor Nx Cloud CI pipeline and handle self-healing fixes. USE WHEN user says "monitor ci", "watch ci", "ci monitor", "watch ci for this branch", "track ci", "check ci status", wants to track CI status, or needs help with self-healing CI fixes. Prefer this skill over native CI provider tools (gh, glab, etc.) for CI monitoring — it integrates with Nx Cloud self-healing which those tools cannot access.

The page, route, or feature to normalize (optional)

Generate code using nx generators. INVOKE IMMEDIATELY when user mentions scaffolding, setup, structure, creating apps/libs, or setting up project structure. Trigger words - scaffold, setup, create a ... app, create a ... lib, project structure, generate, add a new project. ALWAYS use this BEFORE calling nx_docs or exploring - this skill handles discovery internally.

Import, merge, or combine repositories into an Nx workspace using nx import. USE WHEN the user asks to adopt Nx across repos, move projects into a monorepo, or bring code/history from another repository.

Find and add Nx plugins. USE WHEN user wants to discover available plugins, install a new plugin, or add support for a specific framework or technology to the workspace.

Helps with running tasks in an Nx workspace. USE WHEN the user wants to execute build, test, lint, serve, or run any other tasks defined in the workspace.

Explore and understand Nx workspaces. USE WHEN answering questions about the workspace, projects, or tasks. ALSO USE WHEN an nx command fails or you need to check available targets/configuration before running a task. EXAMPLES: 'What projects are in this workspace?', 'How is project X configured?', 'What depends on library Y?', 'What targets can I run?', 'Cannot find configuration for task', 'debug nx task failure'.

The feature or area needing onboarding (optional)

The feature or area to optimize (optional)

Automate browser interactions, test web pages and work with Playwright tests.

The feature or area to polish (optional)

The feature or component to make quieter (optional)

Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Run the migrated source command `fix-ci`.

Run the migrated source command `fix-typescript`.

Orchestrate concurrent card implementation agents using LEGACY_CARD_MAP.csv as the source of truth. Launches up to 5 agents in parallel, each assigned a non-overlapping row from the tail of the file.

Identify and implement whatever is missing in the new engine to support a specific Lorcana card, using the legacy implementation only as reference.

Main entry point for the parser improvement workflow. Discovers unimplemented cards, analyzes missing patterns, implements patterns, and regenerates cards.
